To all whom it may concern:

Be it known that I, JAMES WILLIAM WALKER, J12, a citizen of the UnitedStates, residing at 509 Slade street, instoneSalem, North Carolina, U.S. A., have invented certain new and useful Improvements in .GasGenerating and Heating Apparatus; and I do hereby declare that thefollowing is. a full, clear, and exact description of the same. r Thepresent invention relates to animproved gas generating apparatus,especially designed to generate a gas, preferably from petroleum, whichmay be utilized for heating and illuminating purposes, and which mayalso be usedfor other purposes,

The invention. has for its primaryo'bject to produce a gas frompetroleum or the like which will have greater heatingproperties thanthat now obtained. 7

A further object is to produce the maximum amount of heat from petroleumby adding or combining with the petroleum vapors oxygen-containingvapors or gases, such for instance as the gas derived ,by heatingchlorate of potassium, etc... Another object-is to provide a gas mi turethat will not clog or obstruct a burner,

if used for heating, by the accumulation of carbon, by causing thecarbon and its bye-products to pass through the burner openings in theform of a carbon-dioxid gas by reason of its splitting the steam andcom:bining the oxygen of such steain'with-the heated carbon. I I

The invention consists in mixing? the petroleum vapor with oxygen orother gases ous substance that will increase the'heating properties ofthe petroleum gas, preferably by first beating themindependently .to thepoint where they have about an. equal vol,a-. tility, when they willreadilycombine; These gases may also be produced ,ina common chamber andheatedsufliciently to unite. But this is facilitated by' breaking up thesuperheated gases by a means of strands of metal inthe shape of netting,or by means of a plurality of mineral strands that willnot meltunderthe. intense heat.

Thus the gas derived from the petroleum 'ingsl metallic ne a heatingapparatus constructed in accordance with the invention will bedescribed; V Figure 1 is a perspective viewof a retort and burner,disclosing two gas heating chambers. 7

Fig. 2 is a perspec i've view of a reservoir 6 for holding petroleum andwater to be used in connection with the apparatus shownin I I Fig .f8 isa perspective view of a retort and burner of similar construction tothat disclosed in- Fig. -1 but modified in as much as asupplementaryjgas heatingjchamber is provideriLg Fig. 4 isa crosssection online A -A .'o f' Like numerals of referenceindicate'correspondingparts in [each figure.

The tank or reservoir 13 is preferably,

adapted to contain petroleum and is provided with a receiving tube 18and funnel 19. This tube 18 is disposed in line with and connected tothe adjacent portion of the supply pipe 11, and communicates in somesuitable manner (not shown) at its lower end with the interior of thetank, so that the petroleum in thelatter enters said' tube 18 by way ofsuch communication and then passes into the pipe 11; and in this respectit is similar to the construction shown and described in my priorapplication, Serial No. 217,696, filed February 16, 1918, to .whichreference may be had.

The tank or reservoir 14 is preferably provided with a strainer, andadapted to receive water.

Controlling valves 20 are provided on the pipes 11 and 12, asillustrated in Fig. 2.

The operation of the invention will be clearly understood from thefollowing: The valves 20 are turned on and the asbestos waste in thetray 7 having been ignited, will heat the retort 5 and tubes 1 and 2.The petroleum enters the heated tube or chamber simultaneously with thewater in the tube or chamber 2, and both are heated so that they will beturned into gas. The gases formed then pass into the mixingchamber 3where they unite or combine and then pass through the burner openings 6.It may be preferable at first, to start with the petroleum in order toproperly heat up the tubes 1 and 2 and then to gradually turn on thevalve controlling the water supply.

By combining a proper proportion of oxygen with the carbon, an intenseheat will be obtained with a minimum of petroleum.

In the modification disclosed in Fig. 3 of the drawings -asupplementary-gas heating chamber 21 is provided consisting of a tubesecured at one end to the mixing chamber 8 in which chamber may beprovided a substance such as chlorate of potassium which will besimultaneously heated with the petroleum and water, thereby increasingthe amount of oxygen supplied.

It will be readily understood that without departing from the spirit ofthe invention one gas heating chamber may beused, which could be filledor supplied with oxygen, or with any other substance having similarproperties where it will mix with the petro leum and thereby dispensewith the mixing chamber 3.

It may also be stated that the apparatus herein described may be alteredwithout departing from the spirit of the invention, and it is hereillustrated to better understand the process of increasing the heatingproperties of petroleum gas or the like.

It will be readily seen that a gas of high heating and illuminatingproperties will be obtained, as well as agas particularly cheap andmanufactured at a minimum cost. This gas may also be employed, asalready men tioned, for various other purposes in which gas is used. Animportant vfeature of the gas is that the carbon being so treated willnot clog or obstruct as it usually happens especially in ordinarypetroleum gas.

lVhat I claim is:

1. An apparatus for producing and burning gas, comprising a pair ofhorizontal tubular heating chambers arranged side by side in parallelrelation, a hydrocarbon supply tank connected directly to one end of oneof said chambers, a water supply tank connected directly to thecorresponding end of the other chamber, a mixing chamber into which bothchambers directly open at the other end thereof, a single perforatedhorizontal burner tube located below and substantially midway betweensaid heating chambers, a vertical pipe leading from said mixing chamberto the adjacent end 01 said burner tube, and a tray disposed beneathsaid burner tube and connected to the same to support said chambers andtube, said tray being adapted to contain an inflammable substance forinitially heating said burner tube and heating chambers when ignited, soas to vaporize the hydrocarbon and water. I

2. An apparatus for producing and burning gas, comprising a pair ofhorizontal tubular heating chambers arranged adjacent each other inspaced, parallel relation, a hydrocarbon supply tank connected with oneend of one of said chambers, a water supply tank connected with thecorresponding end of the other chamber, an intermediate tubular heatingchamber between and parallel with the first-named heating chainbers tocontain a vaporizable substance adapted to give off oxygen when heated,a mixing chamber into which all three heating chambers directly open, aperforated horizontal burner tube located below said heatingchambers, avertical pipe connection between said mixing chamber and the adjacentend of said burner tube, and a tray disposed beneath said burner tubeand connected to the same to support said chambers and tube, said traybeing adapted to contain an inflammable substance for initially heatingsaid burner tube and heating chambers when ignited, so as to heat thehydrocarbon and water' and the said vaporizable substance.
